Do not mount the instrument in or above the
filling stream. Ensure that you detect the
product surface and not the inflowing mate-
rial.
Buildup
If the sensor is mounted too close to the
vessel wall, product buildup and other de-
posits on the vessel wall cause false echoes.
Position the sensor at a sufficient distance
from the vessel wall. Please also note chapter
"4.1 General installation instructions“.
Mounting and installation
Vessel installations
Vessel installations, such as e.g. ladders,
often cause false echoes. Make sure when
planning your measuring location that the
radar signals have free access to the meas-
ured product.

Struts
Struts, like other vessel installations, can
cause strong false echoes that are superim-
posed on the useful echoes. Small baffles
effectively prevent a direct reception of false
echoes. These false echoes are scattered
and diffused in the surrounding space and
are then filtered out as "echo noise“ by the
measuring electronics.
